API 13A grade Bentonite is a premium-grade Bentonite (a sodium montmorillonite clay). lt is used as a primary filter-cake-building, filtration-control, suspension agent in freshwater systems and has application in all water-based mud systems. Bentonite appearance varies from off-white to brown depending upon the origin.
